Chloranerectuslactone V, a New Sesquiterpene from Chloranthus erectus Verdc.

A new secoeudesmanolide, named chloranerectuslactone V (1), along with three known compounds, chloranthalactone B (2), 9-hydroxy-heterogorgiolide (3), and β-sitosterol (4) have been isolated from the n-hexane fraction of the methanol extract of the leaves of Chloranthus erectus. Their structures were determined by spectroscopic analysis including MS and 2D NMR.
